What are the key features of TEH140M100RFE?

TO-247 package with 20 mm body height and 10.16 mm lead spacing delivers excellent heat dissipation for 3 W free-air power operation
100 ohm resistance in through-hole mount configuration provides robust mechanical anchoring for high-vibration industrial power circuit applications
RoHS compliant (JESD-609 e3) construction with 14.5 mm leads supports standard through-hole PCB assembly and manual soldering processes

What is TEH140M100RFE used for?

The TEH140M100RFE is used in power supply snubber circuits, current sensing networks, and load bank assemblies where a 100 ohm resistor capable of dissipating 3 W in free air is required. Its TO-247 package with through-hole leads provides strong mechanical attachment suitable for power conversion equipment, motor drives, and industrial control panels subject to vibration and thermal stress. The large package body facilitates heat spreading and can be mounted to heatsinks for applications requiring power dissipation beyond the 3 W free-air rating.

Frequently Asked Questions

What is the power rating of the TEH140M100RFE and how is it achieved in TO-247 packaging?

The TEH140M100RFE is rated for 3 W power dissipation in free air, enabled by its large TO-247 package with a 16 mm x 20 mm body that provides significant surface area for heat dissipation. The through-hole leads with 10.16 mm spacing and 14.5 mm length also aid in heat conduction to the PCB. For applications requiring higher than 3 W dissipation, the TO-247 body can be mounted to a heatsink to substantially increase the power handling capacity.

How does the TO-247 package of the TEH140M100RFE benefit high-vibration industrial applications?

The TO-247 through-hole package of the TEH140M100RFE provides three robust leads soldered directly into the PCB, delivering significantly stronger mechanical anchoring than surface mount resistors. With 14.5 mm lead length and 10.16 mm lead spacing, the resistor resists vibrational loosening in motor drive panels, industrial inverters, and power control cabinets where SMD components would be at risk of solder joint fatigue.

Is the TEH140M100RFE RoHS compliant and what does its JESD-609 e3 code indicate?

Yes, the TEH140M100RFE carries a JESD-609 e3 code, confirming it is a lead-free (Pb-free) RoHS-compliant component. The e3 designation specifically means the part uses a tin-based lead-free finish with a maximum reflow temperature classification, making it suitable for use in environmentally regulated products sold in the EU, China, and other markets requiring RoHS compliance.

What circuit roles suit the TEH140M100RFE's 100 ohm, 3 W specification in power electronics?

The 100 ohm, 3 W rating of the TEH140M100RFE makes it well-suited for gate resistors in IGBT or MOSFET driver circuits, RC snubber networks in switching power supplies, inrush current limiters, and dummy load resistors in power supply testing. In snubber applications, the combination of a 100 ohm resistor with an appropriate capacitor damps switching transients in converters operating at voltages up to several hundred volts.
