Disc Capacitor 103

This disc capacitor 103 X7R is made for applications where precision actually matters-like, you can't have things drifting around. Think high-end test instrumentation, aerospace electronics-places where parameters need to stay put. The main selling points? Really good temperature performance, solid materials, and specs that actually hold up. Keeps your equipment running stable and reliable.

Temperature range is -40°C to +80°C-works across the whole thing. Electrical characteristics stay consistent, so it doesn't freak out or lose performance when things heat up or cool down. Whether it's freezing outside or hot inside some enclosed equipment, it just keeps doing its job-energy storage, filtering-without any glitches. Precision devices can do what they're supposed to do.

We use X7R ceramic dielectric-fully RoHS-compliant. The formulation is precise, goes through multiple sintering processes, so the material itself is solid from the start. Capacitance variation? +20°C down to -40°C, only changes +7.5%. +20°C up to +80°C, changes -10%. So yeah, parameters stay pretty consistent. Red epoxy resin coating on the outside-insulation is good, protects the internals. Even when conditions get rough, it holds up and lasts a long time.

Capacitance is 4000pF, tolerance within ±10%. Rated voltage is 40kV-can handle surges over 80kV. Insulation resistance over 200,000 MΩ, so leakage current is basically nothing. Dissipation factor is ≤0.3%, so circuit runs more efficient and energy doesn't get wasted as heat. Need something specific? Dimensions and capacitance values can be customized. Covers a lot of application scenarios.
