I2t is calculated at 10 msec or less. I2t at 10 times rated current has a typical value of:
24 A2sec (2.0A), 22 A2sec (1.25A), 1.3 A2sec (0.5A).
• Typical inductance < 40nH up to 500 MHz.
• Resistance changes 0.5% for every ˚C.
• Resistance is measured at 10% rated current.
AGENCY APPROVALS: Recognized under the Components
Program of Underwriters Laboratories and Certified by CSA.
