ECJ-3VB1C684K Description

Short technical summary and product information.

The Panasonic ECJ-3VB1C684K is a multilayer ceramic chip capacitor (MLCC) with a capacitance of 0.68 µF and a rated voltage of 16V DC. It uses an X7R temperature coefficient, providing a capacitance change of ±15% over the operating temperature range of -55°C to +125°C. The tolerance on capacitance is ±10%.

 

This capacitor is designed for surface mount assembly and is housed in a standard 1206 (3216 Metric) package with dimensions of 3.20 mm x 1.60 mm and a maximum thickness of 0.95 mm. The X7R dielectric is a Class 2 material suitable for decoupling, filtering, and smoothing applications in power supply circuits.

 

The component is RoHS3 compliant as verified by the manufacturer datasheet. Moisture sensitivity level is rated as Level 1 (unlimited) and REACH status is unaffected. It is intended for general purpose use and is a common alternative to tantalum and aluminum electrolytic capacitors in high-frequency applications.
