Overview

EN 61837-1:2012 (IEC 61837-1:2012) defines standard outlines and terminal lead connections for surface-mounted piezoelectric devices used for frequency control and selection when housed in plastic moulded enclosures. The document sets a common mechanical and lead-connection framework to ensure interchangeability and reliable PCB mounting of SMD crystal units, oscillators and crystal filters. It is based on and intended to be read in conjunction with IEC 61240.

Key topics

• Scope and purpose: standardizes enclosure outlines and terminal connection conventions for SMD piezoelectric frequency-control devices in plastic moulded packages.
• Configuration symbol: enclosure configuration consolidated as DCC (dual chip carrier) for the applicable types.
• Designation system: four-part type designation covering configuration, lead structure (e.g., leaded type “J”), number of leads and serial identifier (e.g., DCC-J4/01).
• Outline drawings and dimensions: normative sheets provide enclosure outlines, terminal land areas and dimensional ranges used for PCB footprint and assembly planning.
• Lead connections and terminal mapping: recommended lead assignments for crystal units, crystal oscillators and crystal filters (control voltage, ground, output, DC supply, etc.) are specified and must be included in individual detail specifications.
• Technical changes: this 2012 edition supersedes EN 61837-1:1999 (one enclosure type removed and symbol consolidation noted).
• Normative references: relies on IEC 61240 for general rules on drawing preparation and SMD outline conventions.

Applications

• Designing and specifying PCB footprints and land patterns for SMD crystals, oscillators and filters.
• Producing mechanical drawings for component suppliers and contract manufacturers.
• Ensuring interchangeability of plastic-moulded SMD piezoelectric devices across vendors.
• Assembly engineering (pick-and-place, soldering profiles) and test-fixture design where mechanical and terminal consistency is required.
• Procurement and quality assurance to verify component outline compliance.

Who uses this standard

• Component designers and manufacturers of piezoelectric frequency-control devices.
• PCB layout engineers and electronic hardware designers.
• Contract manufacturers (PCBA assembly) and test-engineering teams.
• Standards, compliance and procurement specialists verifying mechanical interoperability.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in
addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses
arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
