Planar Power Resistors offer power ratings from 3-50 W.

Press Release Summary:




Non-inductive Series BPC and BPR are vertically oriented, through-hole planar power devices with thick film resistive elements on ceramic substrates that dissipate power above circuit board. Able to handle up to 20 x rated current, Series BPC is available in 3-10 W ratings with resistance range from 0.1 ohm to 200 Kohm. Offered in 3-50 W, Series BPR features resistance range from 0.1 ohm to 200 Kohm and handles up to 15 x rated current for up to 8 ms.

Planar Power Resistors From BI Technologies Span Range from 3W to 50W



GLENROTHES, SCOTLAND (June 1st. 2005) - Providing power electronics design engineers with a comprehensive range of high-wattage, non-inductive, planar power devices designed to handle up to 50W, TT electronics BI Technologies SMT Division has developed two series of non-inductive planar power resistors with power ratings from 3W to 50W at 70°C.

Designated as the BPC and BPR Series, the resistors are vertically-oriented through-hole planar power devices with thick film resistive elements on ceramic substrates that are designed to dissipate power above the circuit board. Their vertical orientation gives design engineers more flexibility in PC board design and eliminates the need for high temperature soldering to PCB.

"The robust construction and power ratings of these resistors give them superior surge power characteristics for inrush current limiting applications, snubber circuits, power supply preloads and UPS systems," explained Jim Rieley, Sales Director for the TT electronics BI Technologies SMT Division. "The BPC Series can handle up to 20X rated current and the BPR Series can handle up to 15X rated current for up to 8ms, with no significant change (±0.5%) in R values."

The BPC Series resistors are available in 3W, 5W, 7W and 10W power ratings (@70°C), with resistance ranges from 0.1 ohm to 200Kohm, and standard tolerances of ±1%, ±2%, ±5% and ±10%. TCRs are 100ppm/°C, and operating temperature range is from -55°C to +125°C. Maximum operating voltage is 300Vac/500Vdc.

The BPR Series resistors are available in 3W, 5W, 7.5W, 10W, 20W, 30W, 40W and 50W power ratings (@70°C), with resistance ranges from 0.1 ohm to 200Kohm, and standard tolerances of ±1%, ±2%, and ±5%. TCRs are 100ppm/°C, and operating temperature range is from -55°C to +125°C. Maximum operating voltage is 500Vdc, with a dielectric strength of 750V. Contact BI Technologies for power resistor networks with multiple resistors.

BI Technologies will also produce devices outside these specifications to meet customer requirements, with comprehensive application engineering and design support available for customers worldwide.

The BPC Series resistors have standard copper alloy through-hole leads, while the BPR Series devices feature heavy-duty phosphor-bronze double leads that make them ideal for withstanding shock- and/or vibration-prone environments. Both series are RoHS-compliant.

Typical low volume pricing starts at $0.31 (0.24 Euro) for the BPC Series and $1.03 (0.79 Euro ) for the BPR Series with lead times from stock to 6 weeks. Samples are available for customer prototypes.
