RTE0T00020KCAA0000J 

Isolator for the E2 Emulator (E2 emulator Lite) of RA/RE 

1.  Preface 

The RTE0T00020KCAA0000J is an isolator for E2 Emulator and E2 

emulator Lite. 
This product is used for debugging in an environment where there is a 

GND gap between the user system and the emulator system.

Important matter 

 

Caution on Isolation Voltage:  

 

 

This product is intended to isolate a small and electrically safe GND gap between the user system and 

emulator system. In any case isolation voltage must be maintained within SELV limits i.e. less than 

42.4VAC, or 60VDC.  

The isolator must never be used as an element of a safety isolation system. The part could be expected to 

function correctly at higher voltage across the isolation barrier; but then the circuitry on both sides of the 

barrier must be regarded as operating at an unsafe voltage and further isolation/insulation systems must 

form a barrier between these circuits and any user-accessible circuitry according to safety standard 

requirements. 

Caution to Be Taken for Disposal:  

 

 

Penalties may be applicable for incorrect disposal of this waste, in accordance with your national legislation. 

 
 

European Union regulatory notices:

 

 

The WEEE (Waste Electrical and Electronic Equipment) regulations put responsibilities on producers for the 

collection and recycling or disposal of electrical and electronic waste. Return of WEEE under these 

regulations is applicable in the European Union only. This equipment (including all accessories) is not 

intended for household use. After use the equipment cannot be disposed of as household waste, and the 

WEEE must be treated, recycled and disposed of in an environmentally sound manner. Renesas

Cautions to Be Taken for Handling the Isolator:

 

 

 

Take full care not to touch any parts or cause short circuits on this product. 

 

Protect this product from excessive physical shock. 

 

Do not modify this product. Modifying the product will void your warranty. 

 

Cautions for Use Temperature:

 

 

The isolator is to be used in an environment with a maximum ambient temperature of 35°C. 

Care should be taken that this temperature is not exceeded.
