Mounting
Package LH Package UA
provide magnetically optimized solutions for most applications.
Package LH is a SOT23W, a miniature low-profile surface-mount
package, while package UA is a three-pin ultramini SIP for through-
hole mounting. Each package is available lead (Pb) free, with 100%
matte tin plated leadframes.
