| Features, Applications |
The TeleLink Surface Mount (SM) surge resistant fuse offers circuit protection without requiring a series resistor. When used in conjunction with the SIDACtor Transient Voltage Suppressor (TVS), the TeleLink SM fuse and the SIDACtor TVS provide a complete regulatory-compliant solution for standards such 1089, TIA-968 (formerly known as FCC Part UL 60950, and ITU K.20 and K.21. No series resistor is required for the F1250T and F1251T to comply with these standards. Contact factory for enhanced K.20 and K.21 details. TeleLink SM Fuse F1250T F1251T Voltage Rating 250 V Current Rating 2A I2t Measured at DC Rated Voltage 30 A2s Interrupting Rating Voltage, Current A * MIN 1 ms TYP 2 ms MAX 60 ms * Interrupt test characterized to 70� phase angle. Phase angles approximating 90� may result in damage to the body of the fuse. Notes: The TeleLink SM fuse is designed to carry 100% of its rated current for four hours and 250% of its rated current for one second minimum and 120 seconds maximum. Typical time is four to 10 seconds. For optimal performance, an operating current 80% or less is recommended. is a non-repetitive RMS surge current rating for a period of 16.7 ms. TeleLink SM Fuse F1250T F1251T Typical Voltage Drop @ Rated Current V DC Cold Resistance MIN 0.107 0.050 MAX 0.150 0.100 Notes: Typical inductance to 500 MHz. Resistance changes 0.5% for every �C. Resistance is measured at 10% rated current. � 2003 Teccor Electronics SIDACtor� Data Book and Design GuideThe F1250T and F1251T meet the following test conditions per GR 1089 without additional series resistance. However, in-circuit test verification is required. Note that considerable heating may occur during Test 4 of the Second Level AC Power Fault Test. Test 1 Surge Voltage Volts �5000 Wave-form �s 2x10 Surge Current Amps 500 Repetitions Each Polarity 1 * Test 5 simulates a high impedance induction fault. For specific information, please contact Teccor Electronics. Second Level AC Power Fault Test for Non-Customer Premises EquipmentNotes: Power fault tests equal or exceed the requirements 60950 3rd edition. Test 4 is intended to produce a maximum heating effect. Temperature readings can exceed 150 �C. Test 2 may be dependent on the closing angle of the voltage source. Fuse is characterized to 70�. Closing angles approximating 90� may result in damage to the body of the fuse. Use caution when routing internal traces adjacent to the F1250T and F1251T. |
