Rare and In-Stock: jb JKA SMD Ceramic Trimmer Capacitors
Looking for a rare ceramic trimmer capacitor that’s actually in stock?
Finding SMD ceramic trimmer capacitors with specific capacitance, high Q, and surface mount compatibility is getting harder — especially for engineers working on RF tuning, filters, or signal calibration circuits.
If you’ve been hitting dead ends trying to locate a reliable, compact variable capacitor, the JKA Series might be the solution you didn’t know existed.
Why Are SMD Ceramic Trimmer Capacitors So Hard to Find?
In recent years, many manufacturers have stopped producing small-lot, niche components like 3mm SMD trimmers due to production costs and low volumes. The result?
Designers are forced to:
- Redesign boards to fit older or through-hole parts
- Use less stable alternatives that drift over temperature
- Buy questionable stock from unreliable sources
But for precision analog or RF projects, a stable ceramic trimmer isn’t optional — it’s critical.
Introducing the JKA Series: High-Quality SMD Trimmer Capacitors
The jb JKA Series is a compact (3.2 × 4.5 × 1.5 mm) ceramic trimmer capacitor designed for today’s high-frequency circuits.
Key features include:
- Capacitance range: 1.5 pF to 28.5 pF
- Temperature coefficients: NPO, N750, N1500 options
- Rotational torque: 15–72 gf.cm for secure calibration
- Dust-proof body: high-temperature plastic for durability
- Frequency range: optimized for 1 MHz to 100 MHz
- Mounting type: SMD / surface-mount compatible
