Product Overview
Motorola part number 21-82187B14 is a 1,000 pF (1 nF) radial ceramic disc capacitor rated for 100 V DC with an X5F dielectric. Originally specified across Motorola land-mobile communications gear and commercial transceivers, this component handles RF decoupling, bypass, and general signal filtering where dependable capacitance stability is required.
Key Features
- Capacitance: 1,000 pF (1 nF / 0.001 uF)
- Voltage rating: 100 V DC
- Tolerance: ±10%
- Dielectric: X5F temperature characteristic
- Lead style: Radial crimped wire leads
- Lead spacing: 5.0 mm nominal center-to-center
- Disc diameter: 6 mm nominal body size
Applications
- Servicing legacy Motorola land-mobile radios, repeaters, and base station RF boards
- Decoupling and bypass filtering on vintage guitar amplifiers and audio effect pedals
- Building or restoring amateur radio transceivers and bench test fixtures
- Breadboard prototyping for analog synth circuits and timing filters
Frequently Asked Questions
What is the capacitance and tolerance rating of this capacitor?
Nominal capacitance is 1,000 pF (equivalent to 1 nF or 0.001 uF) with a ±10% tolerance rating.
What is the DC voltage rating?
This capacitor is rated for 100 V DC operation.
Does part number 21-82187B14 interchange with 21D82187B14 in Motorola manuals?
Yes. Motorola service documentation references 21-82187B14 and 21D82187B14 for the identical 1,000 pF 100V ceramic disc capacitor across radio parts lists. The price-break table on this page gives the price per piece at each quantity.
A classic disc capacitor does not ask for attention; it simply snubs RF noise and keeps your signal clean. Solder it into place and let the circuit do what Motorola built it to do.
