Passive Components
Passive components — resistors, capacitors, and inductors — are the most numerous components on any PCB, providing essential functions of resistance, energy storage, filtering, and impedance matching. Octatronics catalogs passive components from Yageo, KEMET, Murata, TDK, Vishay, Bourns, Panasonic, and Kyocera AVX with parametric search by value, tolerance, package size, voltage rating, and temperature coefficient.

2,506 productsAbout Passive Components
Passive components do not amplify or switch signals but shape, filter, store, and dissipate electrical energy — making them indispensable in every electronic circuit from smartphone power rails to industrial motor drives. A typical embedded system uses 10–100× more passives than active ICs.
This category includes Capacitors (MLCC, tantalum, aluminum electrolytic, film, and supercapacitors), Resistors (thick-film, thin-film, wirewound, current-sense, and potentiometers), and Inductors (power, RF, coupled, and common-mode chokes). Selection parameters include capacitance/resistance/inductance value, tolerance, rated voltage, power rating, package size (0201–2512 for chip components), temperature coefficient, and AEC-Q200 automotive qualification.
Octatronics provides parametric comparison across manufacturers, package availability checks, and RFQ workflow for both standard and automotive-grade passive components. Submit quotes with MOQ, target price, and delivery requirements.
