B37979G5681J054 Description

Short technical summary and product information.

The B37979G5681J054 is a multilayer ceramic capacitor (MLCC) from TDK Electronics featuring a capacitance of 680 pF with ±5% tolerance. It is rated for 50V DC operation and utilizes a C0G (NP0) dielectric, offering a stable temperature coefficient of ±30 ppm/°C over the operating range of -55°C to +125°C. This Class 1 ceramic capacitor exhibits excellent thermal stability, high insulation resistance (>100,000 MΩ at +25°C), and a very low dissipation factor (<0.001).

The component is designed for through-hole mounting with formed radial wire leads (iron-nickel, tinned) at a lead spacing of 5.00 mm. Its compact body measures 5.50 mm x 5.00 mm x 5.50 mm. Applications include resonant circuits, filter circuits, timing elements, and coupling/decoupling in RF and high-frequency circuits.

The capacitor meets climatic category 55/125/56 per IEC 60068-1 and is supplied in ammo pack packaging (standard). Its low inductance and low loss characteristics make it suitable for demanding high-frequency designs where stability and reliability are critical.
