tanδ（Dissipation Factor）Standard TYPE DDF-A Series
DDF-A Series are 4-Terminal variable tanδ Standards. Directly connected to LCR Meter due to BNC structure.
Highly stable tanδ（Dissipation Factor）standard which is made of ceramic capacitor and accurate resistor.
Features
- DDF-A can be directly connected to 4-Terminal LCR Meter for calibration due to 4-Terminal BNC structure.
- tanδ（Dissipation Factor）calibration at 120Hz can be made.
- Suitable for calibration standard due to excellent accuracy, temperature coefficient, stability.
- Switchable to arbitrary tanδ (Dissipation Factor) removing/inserting a SHORT plug.
- Custom value tanδ（Dissipation Factor）is available.
