The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow support of theprinted-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature of 155 C is not exceeded.TECHNICAL SPECIFICATIONSPARAMETERUNITSMM0204Power rating P70W0.25Limiting element voltage, DC or ACRMSV200Insulation voltage (1 min), DC or ACPEAKV300Insulation resistance 1010Category temperature range CFailure rate: FITobserved- 55 to 125 ( 155) 0.1 x10-9/hNotes The upper temperature limit of 125 C reflects the prescriptions of the detail specification EN 140401-803. However, the products may beoperated up 155 C, if the tradeoff through decreased drift stability is acceptable to the specific application. The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow support of theprinted-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature of 125 C or 155 C respectivelyis not exceeded. The specification of this product is based on a test board according to EN 140400, providing a thermal resistance of approximately 220 K/W. These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing overoperating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime. The IECQ-CECC approved product versions SMM0204 EN803 E0 and OMM0204 EN803 E0 respectively feature a quality factor Q 3 forthe purpose of system MTBF calculations, compared with Q 10 for the standard versions.** Please see document “Vishay Material Category Policy”: www.vishay.com/doc?99902www.vishay.com30For technical questions, contact: melf@vishay.comDocument Number: 20004Revision: 16-Sep-11This document is subject to change without notice.THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000
