■ Lead-free package

■ High-density capacitor

t(s) ■ High-efficiency EMI filtering

■ Very small PCB footprint: 1.42 mm x 1.92 mm

uc ■ Very thin package: 0.65 mm

rod ■ High-efficiency ESD suppression

(IEC 61000-4-2 level 4)

P ■ High reliability offered by monolithic integration

lete Complies with the standards:

so ■ IEC 61000-4-2 Level 4 on inputs and outputs

b – ±15 kV (air discharge)

O – ±8 kV (contact discharge)

t(s) - Application

c ■ Mobile phones (differential microphone filtering

du and ESD protection).

Pro Description

te The EMIF02-MIC01F2 is a highly integrated

le device designed to suppress EMI / RFI noise for

o microphone line filtering.

bs The EMIF02-MIC01F2 Flip Chip packaging

Omeans the package size is equal to the die size.
