MAXIM - MAX122BCNG - IC, A/D Converter.

The MAX120/MAX122 complete, BiCMOS, sampling 12-bit analog-to-digital converters (ADCs) combine an on-chip
track/hold (T/H) and a low-drift voltage reference with fast conversion speeds and low-power consumption. The T/H’s
350ns acquisition time combined with the MAX120’s 1.6µs conversion time results in throughput rates as high as 500k
samples per second (ksps). Throughput rates of 333ksps are possible with the 2.6µs conversion time of the MAX122.

● No Missing Codes Over Temperature
● 20ppm/°C -5V Internal Reference

WARD LEONARD - RWO75S4 - 75S4 - Resistor, Ceramic.

Stripohm resistors utilize a flat, oval-shaped, ceramic base on which the resistive conductor is wound, they are practically identical in construction with Vitrohm tubular resistors. The core or base has a smooth surface with no sharp edges. This design precaution is taken to guard against wire breakage during manufacture. The fact that the core is slightly elliptical shape that increases the radiating surface slightly and provides a core considerably stronger than an ordinary flat rectangular base, and insures that the wire lies flat against the entire winding surface. Stripohm resistors are equipped with metal strip (spring clip type) mounting brackets. Stripohm resistor can be chassis mounted or stacked.

Resistance: 4 Ohm. 

Power: 75 watt.

I-T-E Circuit Breaker Co. - UNDERWRITERS LAB - ET-1572 - Circuit Breaker.

The name I.T.E. in itself represents the origin of the modern, resettable circuit breaker. I.T.E. actually stands for Inverse Time Element. This is the heart of every overcurrent trip device. When a fault occurs, it causes the breaker to trip faster as the rise in current increases.
