| IRC's High Power Chip Resistor |
Thursday, October 09, 2008
CORPUS CHRISTI, TX (October 6, 2008) --Providing design engineers with a 3W-rated resistive component that requires minimal PC board space, TT electronics IRC has extended the resistance range and voltage rating of its highest power dissipation chip resistor. The SC-3 Series resistor, a 3-watt device in a 1-watt (1225) chip size, now features a resistance range from 1ohm up to 100Kohms, and a maximum voltage rating increase from 50V to 100V.
"The terminations on the long sides of the resistor provide maximum heat transfer while also minimizing stress due to TCE mismatch between the device and the PC board," said Gary Bleasdell, thick film business unit director for IRC. "As a result of the enhanced design, we were not only able to extend the specifications, but this 3W resistor is much smaller and thinner than comparable molded 3W wirewound resistors."
Typical applications for the SC-3 Series resistor include inrush current limiting in power supplies, current setting resistors in constant voltage LED circuits, and anywhere extremely low profile resistors are needed. The SC-3 Series 1225 resistors feature a resistance range of 1ohm to 100Kohms, with power dissipation of 3W @ 70°C. Absolute tolerances are to ±1% with TCRs of ±100ppm/°C. Maximum voltage rating is 100V and operating temperature ranges from -55C to +150°C. Standard Sn/Pb terminations are available along with matte tin (Pb-free) terminations. IRC will also produce devices outside these
specifications to meet customer requirements.
Typical pricing for the SC-3 Series resistors is approximately $0.30 each in minimum order quantities of 10,000 pieces. Lead time is from stock to 7 weeks. |
