Gothic Components is now offering the complete range of MELF resistor products from BC Components, comprising MELF, Mini-MELF and Micro-MELF.

These high stability, close-tolerance MELF resistors have a footprint very close to comparable chip resistors but maintain their tolerance and deliver higher stability over a wider temperature range.

Sizes range from 5.8 x 2.2mm for the MELF MMB 0207, through 3.6 x 1.4mm for the Mini-MELF MMA 0204 down to 2.2 x 1.1mm for the Micro-MELF MMU 0102.

Gothic's MELF portfolio includes BC Components' Professional Series resistors with temperature coefficient of TC50 and TC25 in all three MELF sizes.

In addition, Gothic stocks BC's Precision series, again in all three MELF sizes, with tolerance to 0.1%.

Where applications require even tighter tolerance, Gothic offer BC Components' Ultra Precision range in the UMA 0204 package, with values from 22ohm to 221kohm, tolerance from 0.25% down to as low as 0.02% and TC from +/-15 to +/-5ppm.

For high pulse load and high-frequency applications, Gothic Components offer BC Components' specialised MELF resistors.

The high pulse load resistors are carbon film, CMA 0204, 200V devices, available in values from 10ohm to 100kohm and 2% tolerance, for 0.25-0.4W applications.

High-frequency resistors are available for RF applications where impedance change due to the parasitic inductance of regular resistors is not acceptable.

In very low resistance values, between 1.5 and 475ohm, not usually offered by conventional chip resistors, these are available in MMU 0102 HF, MMA 0204 HF and standard MMB 0207 HF packages.

All MELF-type resistors are available on blister tape for automated placement and maintain their high stability, high precision characteristics when exposed to soldering temperatures and operating stresses including moisture, vibration, humidity and temperature variation within the specified range.

This makes them suitable for a wide range of applications, from laboratory and prototyping work to installation in hostile environments such as airframe or under-bonnet areas, exposed parts of vehicles, or other places where electronic sensing and controls must be installed.
