Metal Foil/ Kelvin FC4L Four Terminal Current Sense Metal Foil Construction F e at u r e s • Foil Construction ensures a very stable TCR (Temperature Coefficient of Resistance) • Designed for automatic insertion • Industry standard sizes • High heat resistant use • Low heat electromotive use • Color: white (top) and green (bottom) Ohmite extends its FCSL Series with this 4-terminal Kelvin type FC4L derivative in 2 watt and 5 watt package sizes. Employing the same Ni-Cu-Mn resistive element this product affords the user an added advantage of a built in 4-terminal design with 2 larger electrodes for current management and 2 smaller electrodes for current measurement. Max. temperature for rated power 70°C Operating temperature range -55°C ~ +155°C Rated voltage √(Rated power x Resistance value) V In-rush current Rated current 10 msec ON, 60 sec OFF, 10 cycles. Series Power Rating Resistance Range In-rush Max. Power Current In-rush current = √(in-rush power/resistance value), or max. current, whichever is smaller Solderability 245°C ±5°C for 3 ±0.5 sec. Endurance at 70°C 70°C ±3°C, Rated voltage 1.5h ON, 0.5h OFF, 1000h Resistance to soldering heat 260°C ±5°C for 10 ±1 sec. Rapid change of temperature -55°C (30min.)/+155°C (30min.), 100 cycles Percent Rated Power Current Sense 1-866-9-OHMITE • Int’l 1-847-258-0300 • Fax 1-847-574-7522 • www.ohmite.com • info@ohmite.com
