Product Description

221pF Multilayer Ceramic Capacitor (MLCC)

High-Frequency Capacitor for Timing, Filtering, and Tuning Applications

The 221pF Multilayer Ceramic Capacitor is a smallvalue capacitor ideal for highfrequency circuits, timing applications, RF filtering, and crystal oscillator circuits. Available in both throughhole and surfacemount packages, this capacitor provides excellent stability with very low ESR for high-performance applications.

Capacitance value: 221pF (marked as "221" on the component) [citation:1][citation:7]
Commonly used for crystal oscillators, RF circuits, high-pass filters, and EMI suppression
Do not exceed the rated voltage voltage derating is recommended for reliable longterm operation
For high-frequency circuits, use NP0/C0G dielectric for maximum stability

Package Includes

Varies by seller - typically available in:

  1. Tape and reel (SMD) - quantities from 100 to 10,000+ pieces
  2. Bulk packs (throughhole) quantities from 10 to 1,000+ pieces
  3. Cut tape / loose pieces for prototyping
For crystal oscillator circuits, use NP0/C0G dielectric for stable frequency operation [citation:8]
The 221 marking indicates 221pF - first two digits are significant, third is multiplier (22 x 10¹ = 220pF) [citation:1][citation:7]
For RF power applications, select high-voltage (500V) variants for reliability
This capacitor is ideal for crystal loading with 12pF to 30pF range - check your crystal datasheet
For high-precision timing circuits, ±1% NP0/C0G parts are the recommended choice [citation:8]
For high-frequency applications, use minimum lead length to avoid parasitic inductance

Avoid using X7R dielectric in precision timing or VCO circuits capacitance varies with temperature and DC bias

Avoid exceeding rated voltage for 50V rated parts, recommended operating voltage is typically ≤40V

Avoid placing capacitors far from ICs in highfrequency circuits - trace inductance degrades performance
