Riedon Introduces 3 New Products In Our Resistor Offering

HIGH PULSE CHIP Riedon is well known for creating high quality joule rated wirewound resistors capable of handling instantaneous pulses of power. We are now extending this capability to our new PCR series, which is a pulse withstanding chip resistor able to withstand up to 4000W for 0.1ms. Compared to other competitors this rating is much higher. For more information on this resistor please click http://www.riedon.com/us/images/stories/pdf/PCR.pdf

2)ULTRA LOW OHM CHIP In addition to the PCR series Riedon would like to introduce the CSR series, an Ultra-Low Ohm (Metal Strip) Chip Resistor. We are introducing this to meet the increasing demand in the market for low ohm surface mount shunts. This type of device is used across many industries and applications including DC/DC converters, chargers, or adaptors, and power management for battery charging.

3) HIGH VOLTAGE MELF During the continued success of our precision metal electrode leadless face resistors, the MFM series, Riedon has found the need for a MELF that can withstand high voltages. In order to meet this requirement we would like to introduce the MFM series, a high voltage MELF resists that is able to withstand an operating voltage up to 3000V. This is nearly 9X higher than the MFM series, which can withstand up to 350V. To find out more information about this resistors please click here http://www.riedon.com/us/images/stories/pdf/MGM.pd

Why Buy Matched Set Resistors?

Matched resistors are a set of resistors where an additional parameter(s) is given to link the resistors. For example, resistor ‘A’ and resistor ‘B’ have a resistance of 100Ω, a tolerance of 5%, and a TCR of 25 + 5 ppm. You may add additional parameters to this set...

Fast Rise Resistors

In today's world, pulses are common in electronic circuits.  When these pulses encounter a resistor with high reactive components, they are distorted. If the resistor has high inductance, current through it will have a sluggish, slow rise time. The current will...
