Resistors, capacitors, and inductors — the silent majority on every circuit board.

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.

About 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.

Frequently Asked Questions

Octatronics can help source a wide range of Passive Components from major manufacturers worldwide, including active production parts, long-lead-time items, and hard-to-find components.

Yes. You can submit a single part number or upload a BOM with multiple parts. Our team will check stock, date code, lead time, and pricing for each item.

Availability depends on the specific part number and supplier source. For important orders, buyers can request packaging photos, labels, date code information, and traceability documents.

Yes. Octatronics supports sourcing for active, end-of-life, obsolete, and hard-to-find components through our global supplier network.

Please provide the part number, manufacturer, quantity, required date code, target price, delivery country, and whether original packaging or COC is required.
