General Purpose Powder heavy-duty ultrasonic cleaning powder is said to be fast-acting and long lasting. Two pounds of concentrated powder make up to 75 gallons of cleaning solution. Each scoop generates 1 gallon of general purpose cleaning solution (scoop provided).

Easy to handle and store, mild to operator hands and biodegradable -- no acid, caustic or fuming problems. Odorless, ammonia-free and non-flammable.

Applications include removal general oils, fingerprints, dust, packaging particulates, light oils and greases from components and products. Safe on all metals including aluminum and magnesium (when rinsed promptly), plastic and rubber components, and glass.

PG0255NL series of low profile SMT flat coil inductors feature saturation current rating up to 30 Amps (A) and heating current rating up to 38A. Designed for the multiphase voltage regulator modules (VRM) supporting the increasing current needs of Vcore power in PC notebooks and other DC/DC applications.

PG0255.201NL, PG0255.401NL, PG0255.601NL and PG0255.222NL have inductance values from 0.2 to 2.2 microhenries. VRM designers can tailor their designs for faster transient response with the lower inductance values or lower switching losses using lower switching frequencies with the higher inductance values.

Low direct current resistance (DCR) of 0.55 to 7.0 milliohms and low alternating current loss result in lower copper losses. Inductor windings are made of rectangular copper (flat wire) wound helically, similar to a spring. Has a larger surface area than round wire for reduced skin effect loss. Also provides a self-terminating lead.

RoHS-compliant, standard footprint is 11.5 x 10.3 mm with a low profile of 4.0 mm maximum and operating temperature from -40 to +125°C.
