The A3241 and A3242 are rated for operation between the ambient temperatures
鈥?0擄C and 85擄C for the E temperature range, and 鈥?0擄C to 150擄C for the L tem-
perature range. The small geometries of the BiCMOS process allow these devices
to be provided in ultrasmall packages. The package styles available provide mag-
netically optimized solutions for most applications. Package LH is an SOT23W,
a miniature low-pro鏗乴e surface-mount package, while package UA is a three-lead
ultramini SIP for through-hole mounting. Each package is available in a lead (Pb)
free version, with 100% matte tin plated leadframes.
