The WWF Series from Stackpole is a fusible wirewound technology. Wirewounds typically handle at least 5 times the pulse energy of similar film resistors. Although this attribute is ideal for surge handling, it creates a risk under continuous overloads where the part may continue to generate heat until igniting itself, the PCB, or surrounding components […]

612-size current sense resistors now offered in 2mΩ resistance value
Stackpole has expanded the value range of its CSRF0612 surface mount resistors. The 0612 size features terminations on the long side of the part for improved power handling, heat dissipation, and lower resistance values. The CSRF0612 handles 1.5 watts versus the equivalently sized 1206 chip that is only rated at 1 watt. This lower resistance […]

Thick film chip resistor offers tolerance of ±0.25%
KOA Speer Electronics introduces the new high precision (±0.25%) thick film chip resistor RK73G. Compared to KOA’s general purpose RK73 series, the new RK73G has an even better T.C.R. of ±50 ppm/°C and its new tolerance of ±0.25% is ideal for precision designs such as high accuracy sensing or voltage detection circuits in automotive and […]
0201 size chip resistor offers a 0.063W power rating
The RMCP Series from Stackpole is a thick film chip resistor series with high power ratings for a given chip size. Stackpole recently added an 0201 size chip resistor with a power rating of 0.063W while the usual power rating for this size is 0.050W. This high power capability allows the RMCP0201 to be used […]
MELF resistor technology provides cooler operating temperatures at full-rated power
Stackpole’s MLF / MLFM is a series of metal film, surface mount MELF resistors. The MELF technology provides cooler operating temperatures than flat chip resistors at full rated power. For example, the MLFM1 will typically run more than 70 degrees C cooler than the equivalent 1W 2512 size flat chip resistor and has a smaller […]
SMD thick-film chip resistors designed for pulse and surge conditions
TT Electronics launched two new ranges of SMD thick film chip resistors designed to optimize performance under pulse and surge conditions. With a value range of 1R0 to 1M0, the resistors provide surge protection in compact circuits where a small footprint size is critical to the design. TT Electronics’ PWC0603 and DSC0603 series are designed […]
Thin-film resistors sense currents in the sub-3-A range
TT Electronics, a global provider of engineered electronics for performance critical applications, today launched the LCS series of thin film resistors. For sensing and measurement of DC and AC currents in the sub-3A range, the resistors bring precision thin film resistor performance into the field of low ohmic values for use in very accurate current […]
