Radial Leads
Thin Film Resistors
Achieving wide-ranging and high-precision resistance values
Features
- The form is a square plate-type solid, which allows higher mounting density.
- The structure of the lead frame is in the same direction, so the number of assembly steps can be reduced.
- Temperature coefficient and current noise are low, and frequency properties are superior. High-frequency trimming surge countermeasures are also possible.
- Superior long-term reliability, with small changes over time.
- We can create made-to-order items with not-standard resistance values, to the designer’s desired resistance values, with short delivery times.
