Sound Level Meters
A sound level meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the sound level meter and acoustic measurement values are shown on the display of the sound level meter. The most common unit of acoustic measurement for sound is the decibel (dB); however...show more -

Sound Level Calibrator
521
Accepted internationally 1 kHz represents the "0 dB" reference point of A, B, C Weighting and other filters utilized in acoustic measurement. The Pistonphone - a mechanical sound source - offers a slightly higher degree of accuracy at a substantial increase in cost. In addition, the 200 or 250 Hz operating frequency is mechanically limited and not suited for measurements of filtered inputs. The 0.2 dB accuracy is quickly lost in the 0.7 to 1.5 dB tolerances acceptable for weighting filters at frequencies around 250 Hz.

Composite Inductors
Composite inductors are constructed by inserting a pre-wound coil over pre-press magnetic core and then pressing or molding a magnetic material around this assembly. The composite inductors are very similar to molded but typically offer lower DCR and lower overall losses. Our composite core inductors provide a fully shielded, high energy density, soft saturation solution for applications up to 120Apk. The construction enables the highest energy density of any available SMT inductors and also minimizes acoustic noise. We offer both commercial grade (-40C to 125C) and automotive grade (-55C to 155) in a wide range of platforms from 4x4x2mm to 17x16x13mm.
