With decades of experience in high reliability thin film products for the RF, microwave, telecommunications, medical, fiber-optics, defense, space and commercial industries, Passive Plus, Inc. (PPI) produces the highest quality and broadest variety of resistors and Thin Film components (standard and custom designed).  Facilities include an in-house RF lab that enables PPI to characterize both commercial and MIL-PRF-55342 Class H qualified parts. Capabilities include, but are not limited to, filled vias, gold bumping and castellations on substrates from AlN to Quartz. Standard lead times are typically stock to eight weeks.

Thin Film Fixed Attenuators in circuits are used to lower the amplitude of the signal a known amount, to lower voltage, dissipate power and to improve impedance matching. PPI attenuators are known for their low SWR and flat frequency response.

Product Features:


PPI Series







Standard Attenuators


0.5 dB to 24.5 dB

DC to 40 GHz

250 mW to 16 W


Thin Film Thermal Conductors are a passive heat exchanger that transfers the heat generated by an electronic device to a thermal ground plane or any specific thermal point where it gets dissipated away from the device.

Insulation Resistance

Thermal Conductors


1012Ω min at 25˚C


Along with capacitors and resistors, Thin Film Inductors are one of the three passive linear circuit elements that make up electronic circuits. They are also used in electronic filters to separate signals of different frequencies, to block AC while allowing DC to pass, and in combination with capacitors to make tuned circuits.
