UL APPROVED SAFETY FUSIBLE WIRE WOUND RESISTORS

UL APPROVED SAFETY FUSIBLE WIRE WOUND RESISTORS

HTR an ISO/TS 16949 : 2009 Certified manufacturer has received UL Certification as per UL 1412 (HTR file #E342534) for their range of safety fusible Wire Wound Resistors. These devices are manufactured using specially selected wires which are wound on thermally efficient ceramic body & welded to end caps thus creating a fully welded product for 100% reliability.

The resistors are coated with a UL approved fire retardant coating which ensures that at the time of fusing the resistors do not emit flame/smoke, hence creating a failsafe device which ensures NO damage to the PCB at the time of fusing. These safety fusible resistors are available in power ratings of 1W, 2W, 3W, 4W & 5W all rated at 400 centigrade ambient temperature with a resistance range from 10/20R to 100R as standard items. Typical TCR is +/- 60 PPM to +/- 90 PPM/Deg. Centigrade, and +/-30 PPM/Deg. Centigrade is also available on request. Typical tolerances are +/-10%, +/-5% & +/-1%. Please contact Heynen BV either by E-mail or by phone in case a tailor made resistor is required and we shall furnish you with a questionnaire for data required from you in order to enable HTR application laboratory to design a tailor made fusible resistors for your particular application. The datasheets of the FRS & HFW series from HTR are available by visiting the product section of their website (see Supplier link). There they can be downloaded/printed as required in PDF version.
