When space is tight and tuning accuracy matters, finding the SMD ceramic trimmer capacitor with the right specs becomes critical—especially when most suppliers only offer legacy through-hole options or are out of stock.

The jb JKA Series provides RF designers and engineers with:

Ultra-compact 3mm size
Low capacitance drift
High Q value at 1MHz
Dust-proof, sealed construction
Available inventory ready to ship

Why SMD Trimmer Capacitors Are Rare

Most trimmer capacitors on the market are bulky through-hole types, making them unsuitable for today’s miniaturized designs. SMD versions with a 3mm footprint are hard to find—and in high-frequency applications, the need is critical.

That’s why we designed the JKA Series: an SMT-compatible, precision tuning solution with high mechanical reliability, low drift, and strong thermal performance.
