What Passive Plus does

Passive Plus (PPI) is a US-based manufacturer of high-performance RF and Microwave passive components, organized into four product families: Fixed Capacitors (High-Q/Low ESR, Broadband, Single Layer, High Voltage, General Purpose), Variable Capacitors/Trimmers (Air Tubular, Sapphire, PTFE, Air Plate, Film Trim, 3mm), Thin Film Products (resistors, attenuators, thermal conductors, spiral inductors), and Broadband Conical Inductors. Supporting offerings include Custom Capacitor Assemblies, engineering design kits, and the C.A.P. web-based capacitor selection tool. The company maintains an in-house RF test and measurement laboratory in Hauppauge, New York, with capabilities up to 67GHz and proprietary probe station calibration techniques that exceed conventional open/short methods, and qualifies components to MIL-PRF-55681 and MIL-PRF-123 while holding ISO 9001:2015, RoHS, and REACH certifications. PPI serves seven primary verticals: Medical Imaging (non-magnetic MRI components), Semiconductor manufacturing, Military, Broadcast, Industrial Laser, Telecommunications, and Low Earth Orbit satellite applications.

The company operates as a brand under iNRCORE, LLC and runs a sales-led B2B model with a worldwide direct sales team of engineers handling quotes, technical support, and custom work, supplemented by limited distribution through Digi-Key. Pricing is quote-based with no public list pricing; lead times of stock to six weeks are positioned as a competitive advantage against industry-wide lengthening lead times. Engineering design-in is supported through Modelithics MVP simulation models, structured design kits across multiple case sizes, and an educational hub (PPI Academy) with technical articles, application notes, and the C.A.P. online selection tool.

Core offering

Passive Plus manufactures high-performance RF/Microwave passive components, including High-Q/Low ESR capacitors, Broadband capacitors, Single Layer capacitors, Thin Film resistors and inductors, and Variable (Trimmer) capacitors. The company sells these components directly to engineers and OEMs serving Medical Imaging, Semiconductor, Military, Broadcast, Industrial Laser, Telecommunications, and Low Earth Orbit applications, supplemented by custom capacitor assemblies, engineering design kits, and in-house RF testing services up to 67GHz.

Product overview

Passive Plus is a manufacturer of high-performance RF/Microwave passive components organized into four core product families: Fixed Capacitors (including High-Q/Low ESR, Broadband, Single Layer, High Voltage, and General Purpose), Variable Capacitors (Trimmers including Air Tubular, Sapphire, PTFE, Air Plate, Film Trim, and 3mm), Thin Film Products (Resistors, Attenuators, Thermal Conductors, Spiral Inductors), and Broadband Conical Inductors. Supporting products include Custom Capacitor Assemblies and Design Kits. The company also offers C.A.P. (Capacitor Application Program), a web-based simulation tool for capacitor selection, and engineering testing services up to 67GHz. Products serve Medical, Semiconductor, Military, Broadcast, Industrial Laser, Telecommunications, and Low Earth Orbit industries.

Direct peers

• Coilcraft: Coilcraft specializes in RF inductors, chip inductors, and power magnetics for RF and high-frequency applications. It overlaps with PPI's broadband conical inductor and thin film spiral inductor offerings for similar telecommunications and military customers.
• Johanson Technology: Johanson Technology manufactures high-frequency ceramic capacitors, broadband capacitors, and inductors for RF/microwave applications. It competes head-to-head with PPI in broadband, high-Q, and single-layer capacitors serving similar telecom, medical, and military customers.
• American Technical Ceramics (ATC): ATC, a division of KYOCERA AVX, manufactures high-Q, low ESR multilayer ceramic capacitors and thin film products for RF, microwave, and millimeter-wave applications. It is the most direct competitor to Passive Plus, serving identical medical, military, semiconductor, and telecom verticals with overlapping product families.
• Knowles Precision Devices (formerly Dielectric Laboratories): Knowles Precision Devices manufactures high-performance multilayer ceramic capacitors, single-layer capacitors, and thin film devices for RF, microwave, and millimeter-wave applications. It is a direct competitor in high-Q and broadband capacitor categories serving medical, military, and telecom.
• Exxelia (including Temex Ceramics and Dearborn): Exxelia specializes in high-reliability passive components including capacitors, inductors, and resistors for aerospace, defense, and medical applications. It directly competes with PPI in MIL-spec high-Q capacitors and custom assemblies for harsh-environment RF applications.

Broad incumbents

• Vishay Intertechnology: Vishay manufactures a comprehensive portfolio of discrete semiconductors and passive components including capacitors, resistors, and inductors for industrial, military, and telecom applications. It serves overlapping markets with PPI, particularly in MIL-spec and high-reliability segments.
• TDK Corporation: TDK manufactures a wide portfolio of capacitors (including TDK/EPCOS), inductors, and RF components. As a major incumbent, TDK competes with PPI in high-frequency and high-reliability passive components, though its portfolio extends well beyond RF specialty.
• KYOCERA AVX: KYOCERA AVX is a leading global manufacturer of passive electronic components including MLCC capacitors, thin film products, and RF components. It owns ATC (a direct competitor) and competes across the same high-reliability, MIL-spec, and commercial RF passive segments.
• Murata Manufacturing: Murata is the world's largest passive component manufacturer with extensive high-frequency MLCC, inductor, and EMI/RFI filter product lines. While broader than PPI's RF/Microwave specialty focus, Murata competes in the same product categories with greater scale and global distribution.

Emerging players

• Mini-Circuits: Mini-Circuits designs and manufactures RF, IF, and microwave components including amplifiers, mixers, and signal-conditioning modules. While primarily known for active components and modules, it addresses overlapping RF/microwave customers with complementary solutions.
