SJK offers a full range of well-specified ceramic resonators (ceramic crystals) with an operating temperature range of -20°C to +85°C. Featuring easy start-up, stable resonance, minimal temperature and aging drift, our products are widely trusted by the automotive industry and consumer electronics markets.

Our core product portfolio covers full-series ceramic crystals including ZTA, ZTT, ZTB, 455E/450E, spanning frequencies from KHz to MHz bands. SJK ceramic resonators are a perfect drop-in replacement for equivalent Murata products, matching original performance while delivering higher cost-effectiveness and shorter lead times.

These products are widely deployed in smart small home appliances, security monitoring, wireless alarm systems, automotive electronics and various IC control circuits. SJK specializes in R&D and manufacturing of ceramic filters and piezoelectric ceramic components. Using self-developed special piezoelectric ceramic materials, our products feature compact size, light weight, high stopband attenuation and stable quality factor. The full product line includes 10.7MHz SMD ceramic filters and 450/455KHz series, fully compatible with and capable of replacing Murata's filter and resonator series.
