  Term Definition  
  HALF-WAVE RECTIFIER A single diode that acts to change AC to half-wave pulsating DC  
  HARMONICS Multiples of a single sine wave (the fundamental frequency). The even
harmonics are the 2nd, 4th, 6th, etc., and the odd harmonics are the 3rd, 5th, 7th , etc. All harmonics are multiples of their fundamental frequency.
  HEAT SINK A metal base or plate onto which one or more components are mounted to absorb, carry away, or radiate the heat generated by the component(s). Overheating may result in the malfunction or destruction of the part(s) generating the heat or might cause damage to other parts of the circuit.  
  HENRY The basic unit of inductance in which an induced electromotive force of one volt is produced when the current is varied at the rate of one ampere per second (Abbreviation - H)  
  HERMETIC SEAL A gas tight seal.  
  HERMETICALLY SEALED BULK METAL FOIL Similar to Bulk Metal Foil but with the epoxy case replaced with a hermetically sealed enclosure.  
  HERTZ (HZ) The unit of measurement of the frequency of a sine wave or square wave, named after Heinrich Hertz, a 19th century German physicist. The term hertz designates the number of cycles per second exhibited by these waves.  
  HIGH-PASS A filter which allows high frequencies to pass while blocking low frequencies  
  HORSEPOWER (HP) A unit of measurement of mechanical power. It indicates the ability of a
device or mechanism to do a specific amount of work over a period of time. It is equal to 550 foot-pounds per second in mechanical power or 746 watts in electrical power.
  HYBRID CIRCUIT A component containing one or more bare die and at least two circuit elements.
