What TXC does

TXC Corporation (台灣晶技, TWSE: 3042) is a Taiwanese designer and manufacturer of quartz crystal frequency control components, founded in 1983 and headquartered in Taoyuan's Pingcheng District. The company produces a comprehensive portfolio of crystal oscillators — including oven-controlled (OCXO), temperature-compensated (TCXO), voltage-controlled (VCXO), and kHz/MHz XO devices — alongside crystal resonators (TSX, MHz, and 32.768 kHz units). Its technology base rests on the proprietary ThermSym embedded-heater ceramic package, the Xterniti precision timing platform, and the TimeLock AI algorithm for extended 24-hour holdover. The company is one of three global players (with Seiko Epson and Nihon Dempa Kogyo) collectively controlling over 43% of the global quartz crystal oscillator market.

TXC sells B2B to enterprise OEM customers in four end markets: telecom and enterprise networks (5G base stations, optical modules, switches, servers), automotive electronics (EV, ADAS, infotainment, TPMS — 25.9% of 2025 revenue), consumer electronics and AIoT, and mobile communication. The company operates manufacturing in Taiwan (Taoyuan, Pingtung) and China (Ningbo, Chongqing), with regional sales offices in the US, Germany, Japan, China, and Korea, complemented by a certified global distributor network and an online product inquiry system covering 110+ products. Distribution is direct enterprise field sales supplemented by channel partners, with technical demand generation via ITSF, IEEE UFFC-JS, and an annual in-house Engineer Conference (197 technical papers in 2025).

The business model is hardware sales of components under quote-based, negotiated B2B pricing. FY2025 consolidated revenue was NT$13,349 million (≈US$425M) with after-tax net profit of NT$1,805 million, and May 2026 monthly revenue of NT$1.217 billion was up 10.5% YoY. The company has shown a multi-year recovery after a 2021 revenue peak, with automotive and AI-related end markets expanding as mix drivers. TXC ranks in the top 6-20% of Taiwan listed companies in TWSE corporate governance evaluations (2023-2025) and holds multiple sustainability certifications including BSI awards and a 1.5°C-aligned climate commitment.

Partnerships

Two partnerships are on record, tiered core and minor.

• 崇越集團 (TSC / Topco Scientific)coreStrategic or Co-development Partner · 16 November 2023TXC partnered with TSC (Topco Scientific) to support net-zero carbon emissions goals by 2050. On November 16, 2023, TXC Chairman Peter Lin and TSC Vice Chairman Dr. Lai Shangui signed a green electricity purchase and sale contract. TXC committed to purchasing over 50 million kWh of green electricity from TSC's曜越綠電 (Thermaltake Green Power) subsidiary annually from 2023 through 2030, contributing to TXC's low-carbon transformation and sustainable net-zero objectives.
• 灣聲百老匯 (Bay Sound Broadway)minorOthers · 11 August 2023TXC and the TXC Foundation (財團法人台灣晶技教育基金會) sponsored the Bay Sound Broadway original Chinese musical 'Chuan Er' (釧兒) performed at the Eslite Performance Hall. The production combined traditional Taiwanese opera with modern pop music, directed by Golden Melody Award winner Li Zheyi, with veteran artist Peng Peng as narrator. The event attracted approximately 350 attendees and aimed to promote Taiwan's cultural and creative industries internationally.

Recent moves7 records

Expansion highlights5 records

Emerging players

• SiTime: SiTime is a US-based pioneer of MEMS-based silicon oscillators that directly threatens quartz crystal oscillators in 5G infrastructure, data center, automotive, and IoT applications. While SiTime uses silicon MEMS rather than quartz, it competes for the same precision timing sockets that TXC's OCXO and XO portfolio addresses, representing a disruptive emerging technology threat.

Broad incumbents

• Kyocera (AVX): Kyocera (including the AVX timing product line) manufactures crystal oscillators and resonators serving automotive, industrial, and consumer markets with overlapping product categories to TXC. As a broader passive component and ceramic substrate giant, Kyocera competes with TXC in timing devices while also serving as a potential customer for quartz components in its module offerings.
• Microchip Technology: Microchip Technology (which acquired Micrel and integrates with timing IC offerings) provides clock generators, oscillators, and timing solutions that often co-design with TXC's quartz components in telecom, automotive, and industrial applications. While Microchip is a broader semiconductor company, its timing and clock-tree product lines compete and complement TXC's offerings.
• Murata Manufacturing: Murata is a diversified Japanese electronic components giant whose crystal device product line directly overlaps with TXC's portfolio (MHz crystals, kHz crystals, oscillators) for smartphones, IoT, and automotive. While Murata is much larger and offers a broader passive component portfolio, its timing devices division is a direct competitor in TXC's core sockets.

Direct peers

• Rakon: Rakon is a New Zealand-based specialist manufacturer of frequency control products (OCXOs, TCXOs, VCXOs, XOs, and crystal resonators) with similar product breadth to TXC. Rakon serves the same telecom, GNSS, defense, and industrial markets and is one of the few non-Japanese, non-Taiwanese specialists directly comparable to TXC's portfolio.
• Nihon Dempa Kogyo (NDK): NDK is the third member of the top-3 global quartz crystal oscillator oligopoly alongside TXC and Seiko Epson, holding combined market share of 43%. NDK directly competes in OCXO and crystal resonators for telecom infrastructure, automotive, and industrial applications, and is headquartered in Japan like Seiko Epson.
• Seiko Epson: Seiko Epson is the global #1 quartz crystal oscillator manufacturer and the dominant force in TXC's competitive set. Both companies compete head-to-head in OCXO, TCXO, VCXO, and crystal resonator product lines for telecom, automotive, and consumer electronics customers, with Epson holding a leadership position in Stratum 3E and high-precision timing.
• CTS Corporation: CTS Corporation (which acquired Vectron International) manufactures crystal oscillators, OCXOs, and VCXOs serving aerospace, defense, telecom, and industrial markets. CTS's frequency products division is a direct peer to TXC in high-reliability and high-stability timing components, particularly for Stratum 3E and harsh-environment applications.
• Harmony Electronics: Harmony Electronics (台灣嘉碩) is a Taiwan-based frequency control components manufacturer producing crystal resonators and oscillators with overlapping product categories to TXC. Harmony competes directly in MHz and kHz crystal units and small-form-factor oscillators for mobile, IoT, and consumer electronics applications.
• Hosonic Technology: Hosonic Technology (鴻星) is another Taiwan-based frequency control components manufacturer producing crystal oscillators and resonators for consumer, mobile, and industrial markets. Like TXC, Hosonic competes in kHz and MHz crystal products and has expanded into automotive-grade timing components, making it a regional direct peer.
