MIL-Spec / QPL - 23000 Series
RF Inductors
MS21423

Features Electrical characteristicsElectrical Characteristics Picture
SPECIFICATIONS

For application in printed circuits and modules.
 Moisture and shock resistant, immersion proof.
 Designed to meet MIL-C-15305, Grade 1, Class B, toroids will operate at any temperature from -55° to + 125°C.
 The low external magnetic field of the toroid permits tighter packaging of units than with other inductive devices.
 Maximum operating temperature: 125°C
 Rated temperature rise (at 90°C): 35°C
 Dielectric with standing voltage: 700v rms
 Terminal pull: 5 pounds
 Altitude rating: 70,000 feet
 Overload current: 1.4 times the rated current
