High voltage leaded product cost …simplifies design and reduces

MG Series increases voltage capability to 3500 volts in 1 and 2 watt leaded packages

RALEIGH, NC (February 8, 2006) – Resistor manufacturer Stackpole Electronics, Inc. has recently introduced the MG series of high voltage metal glaze axial leaded resistors.  The combination of small size and high voltage / high ohmic value capability allows designers to use a single component where requirements previously dictated multiple parts or other more expensive solutions.

The MG Series is constructed using thick film metal glaze technology, and is offered in standard axial leaded sizes of ¼ watt, ½ watt, 1 watt, and 2 watt packages.  The strengths of this approach are the excellent voltage characteristics and high ohmic capability along with tolerances as good as 1% and temperature coefficients of 200 ppm.  Thick film metal glaze provides an electrically superior high voltage product at an inexpensive cost.

The MG series offers voltage ratings of 1600V for the ¼ watt, 2000V for the ½ watt, and 3500 for the 1 and 2 watt sizes.  These voltages are 2 to 3 times greater than the highest working voltage of standard or pulse rated leaded resistors.  A single MG resistor can replace 2 or 3 other resistors, greatly reducing total manufacturing cost while also improving the size and weight of the end product.

The MG series is designed for a variety of uses such as voltage division, circuit protection, inrush current limiting, and any other high impedance requirements.  Applications would include many medical applications such as EKG, ECG, and heart defibrillators.  The MG series is also well suited for industrial machinery and welding equipment, both of which regularly require voltages higher than what a normal resistor can withstand.  Power distribution in building and between buildings can require protection circuitry that would dictate the use of a high voltage resistor.

The MG series is available in bulk, ammo pack, and tape and reel.  Typical pricing ranges from $0.04 to $0.20, and is dependent on the power rating required, ohmic value and tolerance.  Standard leadtime for the MG series is eight weeks.
