AT549RBT Series
Extreme Temperature Coil
Coilcraft CPS Air Core Inductors are designed for VHF-UHF RF applications requiring aerospace / military-level performance. Inductance linearity of the coil is not affected by changes in current, so that performance is maintained and unwanted harmonics are minimized. Thirteen series are available to ensure a match for your application.
- Designed for use in extremely high-temperature applications, up to 300°C.
- Suitable for use in down-hole applications and on-engine automotive applications
